G'day to you and congrats
on your 1st new to you IHCC. Like their larger brothers, CC's are almost as addictive .. be careful you could end up with a stable full.
My buddy Gord and I rebuilt his QA42 Blower a couples years ago. Had to make a bunch of parts but they are available. We are just too frugal to buy something that we can make for next to nada. There are lots of resources on the site, and the manuals linked above are good ones and will be able to answer most of your questions.

Keep us posted on your progress.
